Question

The equivalent conductivity of $0.1NC{H}_{3}COOHN$ at ${25}^{\circ }C$ is $80$ and at infinite dilution $400oh{m}^{-1}$. The degree of dissociation of $C{H}_{3}COOH$ is__________.

• A. $1$
• B. $0.2$
• C. $0.1$
• D. $0.5$

Answer 1

The correct option is B $0.2$

${\Lambda }_{1N}=80S{\Lambda }_{\infty }=400S\alpha =\frac{{\Lambda }_{1N}}{{\Lambda }_{\infty }}=0.2$
